Answer:
1) Change the length of side AB to 2 feet
Step-by-step explanation:
Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.
To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:
We will assume AB is unknown.
PR = 7.5 ft
AC = 2.5 ft
PQ = 6 ft
Plug in the values into the equation
Cross multiply
Divide both sides by 7.5
The architect should change the length of AB to 2 ft
Answer:
b) 4,000,000
Step-by-step explanation:
Let the population is measured since 1995,
Given,
The initial population, P = 3,942,000,
Annual rate of growing, r = 0.7% = 0.007,
If y represents the population after t years
So, the population after t years would be,
Therefore, the population after 5 years,
Hence, the population in 2000 would be approximately 40,00,000.
Option 'b' is correct.
